Wood was on a rehab assignment before it ended because of soreness in his shoulder.

The team issued a statement Thursday, saying "Roy had successful shoulder surgery yesterday. He had an arthroscopic evaluation and underwent debridement of his labrum and rotator cuff as well as removal of an inflamed bursa."

Halladay will begin his rehab shortly, and could begin throwing again in six to eight weeks. Through 34 1/3 innings this year, Halladay has an 8.65 ERA and a 6.22 FIP. 

Rice has made a major-league high 23 appearances this season. If he continues being used at this rate, Rice would break the Mets' record for appearances in a season. Manager Terry Collins has been happy with Rice's production, saying "Scott’s done a great job, he really has. So in those situations, he’s going to have to be the guy that steps up, and either gets his groundball or strikeout."

In 18 1/3 innings this season, Rice has a 3.44 ERA and a 3.84 FIP.

Perez is batting .380 (19 for 50) in his last 13 games, raising his average from .256 to .303. He has four doubles, four runs and six RBI in that span.

Cain also doubled twice Wednesday, which ended a streak of 15 games without one. Cain is batting .319 (15 for 47) with two doubles, two triples, 10 runs and 10 RBI in 12 May games.

His batting average has gone from .220 to .252.

Freese did not play Wednesday for matchup reasons, according to MLB.com. He's struggled this year, hitting .216/.296/.250 in 88 at-bats. Freese will bat sixth against Mets pitcher Jonathon Niese. 

Wells started at DH Wednesday, but when manager Joe Girardi needed a pitcher in the ninth inning of Wednesday's 12-2 loss, he turned to infielder Alberto Gonzalez to get the final out, which prompted Wells to come off the bench to play second base.

"We needed one out," Girardi told The Star-Ledger. "It’s not something I want to do. But for me to bring in another pitcher, it doesn’t make a ton of sense there. We’re down 10 runs, with three outs to go. They have a full bullpen, with their closer rested. I just figured, put him at second base."

"I feel like I’ve (been able to grind with bad stuff) sometimes," Hughes said to The Journal News. "But there are other nights where it feels like everything you do is not working and not happening. That’s where nights like this happen. Hopefully this is a 1-in-100 type thing. I remember I’ve had bad nights where I’d get 12 outs or something, but I don’t think I can remember having an outing like this before. It’s tough to swallow, but it happens to everybody. No one’s going to feel sorry for you, so I have to throw my bullpen in two days and move on."

Hughes added he will sit down with pitching coach Larry Rothschild and try to figure out where to go from here.

"I’d like to just get back to three starts ago, not really worry about what was bad about this one or what was bad about that one," he said. "Just clear my head of these last two and go forward, really get back to what I was doing."

In his last four games, Murphy has seven hits and is hitting .278/.314/.410 in 144 at-bats. Murphy will bat second against Cardinals' ace Adam Wainwright Thursday.
